Eye Protection: Sunglasses have the practical effect of soothing your eyes from the bright sun. This is also an important safety feature as it greatly improves visibility while driving (roads create terrible glare) and during sporting activities.
Sunglasses also offer protection from ultraviolet radiation, which can cause cataracts and other eye damage, including macular degeneration, growths of tissue on the white part of the eye (pterygium), and skin cancer around the eyes if used with excessive exposure.
Ultraviolet radiation is classified into three types, UVA, UVB and UVC, but protection against UVC is not required because this type of ultraviolet radiation is completely absorbed by oxygen and ozone in the atmosphere. When buying sunglasses, it's important to make sure they block 99-100% of UV rays.
Different Lens: Sunglass lenses are available in a variety of colors to choose accents. Grays or smokes reduce all light evenly and don't contrast the altar, while yellows and browns enhance contrast.
You may have clear lenses that still offer full UV protection. Transition lenses start at about 30% tint and darken up to 80% with intense sunlight. This effect is now available with plastic or polycarbonate lenses, as well as glass.
